Thickness-dependent wrinkling of PDMS films for programmable mechanochromic responses

Zhiwei Li, Yun Liu, Melinda Marin, and Yadong Yin^*

University of California, Riverside, USA

This work reveals the thickness dependence of the wrinkling behaviors of plasma-treated polydimethylsiloxane (PDMS) films. For thick films, the wrinkles can be predicted by the classic nonlinear finite mechanics, giving rise to brilliant structural colors. For thin films, the wrinkles are large and random. These observations provide new opportunities for understanding the wrinkling mechanics and have promising applications in smart optical materials.
